Gpredict is a real time satellite tracking and orbit prediction program
written using the Gtk+ widgets. Gpredict is targetted mainly towards ham radio
operators but others interested in satellite tracking may find it useful as
well. Gpredict uses the SGP4/SDP4 algorithms, which are compatible with the
NORAD Keplerian elements.
Gpredict includes the following features:
* Tracking an infinite number of satellites only limited by the
physical memory and processing power of the computer.
* Display the tracking data in lists, maps, polar plots and any
combination of these.
* You can have many modules open at the same either in a
notebook or in their own windows. The module can also run in
* You can use many ground stations. Ground station coordinates
can either be entered manually or you can get some appriximate values
from a list with more than 2000 predefined locations worldwide.
* Predict upcoming passes for satellites, including passes where a
satellite may be visible and communication windows
* Very detailed information about both the real time data and the
* Gpredict can run in real-time, simulated real-time (fast forward and
backward), and manual time control.
* Doppler tuning of radios via Hamlib rigctld.
* Antenna rotator control via Hamlib rotctld.

Gpredict is written using the Gtk+ widget set, which is available for most
Unix like operating systems, Mac and Windows. Following libraries are required
for successful compilation of Gpredict:
- Gtk+ 2.18 or later
- GLib and Gthread 2.22 or later
- Libcurl 7.19 or later
- GooCanvas 0.15 or later
- Hamlib (runtime only, not required for build)
If you compile Gpredict from source you will also need the development parts
of the above mentioned libraries, e.g. gtk+-dev or gtk+-devel and so on.
